Please repost letting us know how far each route is.

Let's assume that the short route is 14 miles and the longer route is 21. He takes the longer route TO the mountain, and the shorter route FROM the mountain.
Add the trip there to the return trip.
21 + 14 = 35
Now divide by the mph.
35/7 = 5 hours
The trip total would be 5 hours. How long for each leg of the trip?
21 miles / 7 mph = 3 hours for the trip there
14 miles / 7 mph = 2 hours for the return trip

Please repost with actual values if the explanation does not make sense with your numbers.
